This is a SNP pileup vcf output based on 4 (Sanger) sequences. These 4 sequences have some overlapping sequences, but not all. I have 2 questions about how to interpretate the information.
Q1. For sample B.bam and C.bam, since PL=60,3,0, why GT is determined as 0/1, not 1/1?
Q2. sample D.bam, PL=0,0,0, how GT is determined as 0/1? Does it mean this sequence does not cover this fragment?
